O'Connor & Associates
From Wikipedia, the free encyclopedia
O'Connor & Associates was a Chicago-based options trading firm, with a particular emphasis on financial derivatives. The firm was founded in 1977 by John F. O'Connor and his brother-in-law, Robert J. Creamer. In 1992, O'Connor & Associates was acquired by Swiss Bank Corporation.[1] The acquisition was part of Swiss Bank's efforts to expand its options trading capabilities in the United States. At the time of the acquisition, O'Connor & Associates had over 500 employees and was one of the largest options trading firms in the world. [2]
After the acquisition, O'Connor & Associates continued to operate as a subsidiary of Swiss Bank Corporation. In 1998, Swiss Bank Corporation merged with Union Bank of Switzerland to form UBS.[3] As part of the merger, O'Connor & Associates was integrated into UBS's investment banking division. The firm continued to operate as UBS O'Connor.[4]
